At about 11:15 pm on July 4th, while watching a fireworks display in a rural area south of Interlochen, MI, I noticed a fast moving light traveling south to north in an unsteady, wobbly flight path. Approximately a minute later I observerd a second light traveling along the same flight path, demonstrating the same flight characteristics. The lights were fairly dim, about as bright as an average star, and about the same size. Neither light blinked, flashed or twinkled in any way. Both objects were at about 70 degrees above the horizon, and and managed to travel from mid-sky to the northern horizon in about 15 seconds. Both objects appeared to wobble or weave slightly as they traveled, and made no discernable sound. It is highly unlikely that this was a firework of any kind. The display we were watching was a non professional one, and at this point there had been a lull of about five minutes since the last firework had been launched. They could not have been sparks because they lasted too long, and their flight path started down wind of the launch site. In all probability I would not have noticed these objects had I not been focused on the sky since they were not particularly bright, and would probably not have been visible at all near city lights. The only thing that made them eye catching was the speed at which they moved and the wobbling motion. I believe that I was the only one that noticed the first object, but the second object was seen by three other people in our group.
